I know it is going to be a slow, long process in get a refund of the cancelled flight but due to medical problems of my companion we will not be able to go on a trip to Thailand in April. Is it possible to make this cancellation on their website"? There is a link for cancellations and change of the dates on a ticket but all I see is changing the dates not complete cancellation of the ticket. Is the only way to make the cancellation with an international call?
